CHAPTER 11

TREES1

10-11-1: PURPOSE AND INTENT:

A.   Purpose And Intent: This chapter governs the maintenance, protection, removal, and replacement of existing trees within the village, in order to protect and preserve the wooded character of the village and to fulfill the objective identified in the village comprehensive plan of maintaining, protecting, and, as needed, replacing trees within the village.
B.   Objectives: The protection of trees as a valuable resource and integral part of community infrastructure also accomplishes the following objectives:
1.   Stabilize valuable topsoil by preventing or minimizing unnecessary soil erosion and sedimentation;
2.   Assist in proper stormwater runoff in order to decrease the costs associated with flooding;
3.   Protect the important link in the hydrologic cycle that trees provide through the transpiring of water and the neutralization of wastes that pass through to the ground water table and other aquifers;
4.   Aid in the reduction of air pollution through the removal of harmful carbon dioxide and the generation of oxygen;
5.   Provide a buffer and screen against noise pollution;
6.   Restore, to the greatest extent possible, denuded soil that results from construction and grading work accompanying development;
7.   Provide a haven and nesting areas for birds, insects, and other forms of wildlife that are essential to the maintenance of the food chain and that help control and eliminate disease carrying mosquitoes;
8.   Reduce energy consumption through the windbreak and shade effects of trees;
9.   Protect and increase property values in a manner that maintains each property owner's enjoyment of his or her property;
10.   Conserve and enhance the village physical and aesthetic environment, particularly its valuable natural and rural atmosphere;
11.   Provide important psychological and emotional benefits to residents of and other persons within the village;
12.   Eliminate trees that constitute a threat, danger, or nuisance to the public or to property in the village, or that may be dangerous to the health of other trees and vegetation in the village; and
13.   Protect and enhance the quality of life and the general welfare of the village and its residents.
14.   Recognize trees are an integral part of community infrastructure and as such should be preserved, protected, and cared for as is other critical infrastructure. (Ord. 2008-22, 9-9-2008; amd. Ord. 2024-5, 3-11-2024)

10-11-2: APPLICATION AND ENFORCEMENT OF PROVISIONS:

A.   Generally: This chapter applies to all areas and zoning districts within the village, and will be applied and enforced by the village forester, with the advice and assistance of the building commissioner. This chapter applies simultaneously with other consistent provisions of this code as well as state and federal law. If any inconsistency exists, the provision resulting in the maximum protection and preservation of the highest quality of trees will govern. No permits or approvals granted under any village regulation other than this chapter will authorize the damage, removal, or replacement of any trees in a manner which is not consistent with the provisions of this chapter.
B.   Public Trees: The village forester has the authority and responsibility to plant, prune, maintain, and remove trees and woody plants growing in or upon all village-owned property. All trees on public property will be planted and maintained in accordance with the tree care standards and nursery stock standards set forth in this code. Any contractor performing maintenance on a protected public tree must:
1.   Be supervised by a certified arborist; and
2.   Maintain liability and workers compensation insurance.
C.   Modification Of Required Submittals: The village forester may, upon consultation with the building commissioner, modify or waive portions of the tree permit application, tree replacement plan, tree replacement mitigation fee, or tree protection plan required by this chapter if the village forester determines, and the building commissioner agrees, that the modification or waiver will be consistent with the purposes of this chapter.

10-11-7: TREE REPLACEMENT:

A.   General Requirements: Any protected tree damaged or removed in the course of a regulated activity must be replaced by the applicant pursuant to this section and as depicted in a tree replacement plan pursuant to subsection I of this section, regardless of whether the protected tree is located on the same lot on which the regulated activity takes place; except, that the village forester may, pursuant to subsection G of this section, consider a request to submit a fee in lieu of the replacement of trees, and except for the exemptions in subsection B of this section. No replacement tree may have a caliper less than one and one-half inches (11/2").
B.   Exemptions: Tree replacement is not required if the Village Forester determines that any of the following circumstances exist:
1.   When a protected tree, due to natural causes, is dead, dangerous, or interferes with any existing or proposed public improvements, is in dangerous proximity to any public utility lines or related facilities, or is a diseased tree or dangerous tree or otherwise unsafe, unhealthy, or insect infected and constitutes a hazard to persons, property, or other trees.
2.   When a protected tree, due to natural causes, obstructs any street, sidewalk, or any pedestrian path to an extent that the protected tree interferes with free passage and clear view along the street, sidewalk, or path and at any street or driveway intersection.
3.   When removal of a protected tree is necessary to comply with the current standards generally observed by professionals in the forestry profession.
4.   When the removal involves only the removal of class D trees or exotic and invasive species and does not involve any protected tree.
5.   When the protected tree to be removed is located within the foundation footprint of: a) a new residential building to be constructed on an undeveloped lot in a zoning district, or b) an addition which creates additional gross floor area for an existing residential building, provided that the combined gross floor area for the new residential building or existing residential building and the addition, as applicable, is compliant with the maximum gross floor area restrictions for residential buildings under the zoning regulations and that the new residential building or the addition, as applicable, does not require any variations. In these events, replacement trees will be required only for fifty percent (50%) of the removed protected trees within the foundation footprint, at the replacement rate set forth in subsection C of this section.
6.   When the protected tree to be removed is located within the foundation footprint of an addition which creates additional gross floor area for a residential building that is a Protected Building pursuant to the Village’s historic preservation regulations (Title 9, Chapter 14 of this Code); provided, that (i) the addition does not require any variations and (ii) the Historic Preservation Commission has approved the addition by an affirmative vote. In this event, replacement trees will not be required for the removed protected trees within the construction footprint.
C.   Replacement Formula: Protected trees must be replaced by group A trees pursuant to the replacement rate specified in this subsection. The tree replacement rate is determined by the species of tree removed. For each inch of dbh removed, replacement trees must be provided at the rate shown in the following table. For example, for every inch in diameter of a removed group A tree, each inch removed must be replaced with 1.25 inches in diameter of replacement trees:
 
Species Removed
Diameter Of Tree Removed
Replacement Rate
All public trees
1 inch
125 percent
Group A
1 inch
125 percent
Group B
1 inch
75 percent
Group C
1 inch
50 percent
 
D.   Specifications: All replacement trees must be:

6.   Planted in a location approved in advance by the village forester; and
7.   Inspected by the village forester prior to planting.
E.   Care Of Replacement Trees: The applicant will be solely responsible for the care and feeding of newly planted trees for a period of two (2) years, which time shall commence upon the issuance of a final certificate of occupancy for the property as required pursuant to the village building regulations or, if no final certificate of occupancy is required, upon completion of the tree replacement plan as determined by the village forester pursuant to subsection I of this section. The care and feeding of newly planted trees must, at a minimum, adhere to the tree care standards.
F.   Alternative Locations: The village forester may reduce the number of replacement trees to be planted on the subject property and designate alternative locations for new trees on the subject property upon determining that full tree replacement will result in unreasonable crowding of trees or would be otherwise inconsistent with current standards generally observed by forestry professionals. If the village forester cannot identify an appropriate alternative location on the subject property for a tree, that tree may be replaced by a fee in lieu of replacement pursuant to subsection G of this section.
G.   Fee In Lieu Of Replacement:
1.   Modification Of Tree Replacement Requirement: The village forester may waive or modify any portion of the tree replacement requirements if the village forester determines that replacing trees at the full replacement rate provided by subsection C of this section would:
a.   Result in the unreasonable crowding of trees upon the subject property or upon a public right of way immediately adjacent to the subject property; or
b.   Adversely impact the viability of existing trees on the subject property; or
c.   Not be consistent with the current standards generally observed by professionals in the forestry profession.

J.   Security Requirements:
1.   Security Required: Every tree replacement plan must be accompanied by a tree replacement security, except as modified or waived by the village forester pursuant to subsection J5 of this section. The tree replacement security must consist of:
a.   A cash deposit to be held in escrow by the village;
b.   An irrevocable letter of credit issued by a lender authorized to issue the letter by any state or by the United States;
c.   A bond with good and sufficient surety; or
d.   Another form of security approved by the village administrator.
2.   Amount: The amount of the tree replacement security will be determined by the village forester and must be equal to three (3) times the total actual cost of strictly complying with and fully implementing the tree replacement plan, with any applicable adjustment for cost of living increases and/or inflation.
3.   Replenishment Of Security: If, at any time, the village forester determines that the funds remaining in the tree replacement security are not or may not be sufficient to pay, in full, the total actual costs of strictly complying with and fully implementing the tree replacement plan, then, within ten (10) days following a demand by the village, the applicant must increase the amount of the tree replacement security to an amount determined by the village forester to be sufficient to pay the uncovered costs. Failure to so increase the amount of the tree replacement security will be grounds for the village to retain or draw down any remaining balance of the tree replacement security.
4.   Return Of Security: Upon completion of the tree replacement plan pursuant to subsection I3 of this section, the tree replacement security, or any remainder thereof, will be returned or released to the applicant.
5.   Limited Waiver: Where a tree permit application concerns the damage or removal of trees unrelated to construction activity, the village forester may, upon consultation with the building commissioner, modify or waive the requirement for submittal of the tree replacement security if the village forester determines that the tree replacement security is not necessary for the limited damage or removal and that the purposes of this chapter will be fulfilled without submittal of the tree replacement security.
K.   Failure To Comply:
1.   Notice: If, at any time, the village forester determines that the applicant has failed to comply with or implement the tree replacement plan, the village forester will cause notice of the failure to be served upon the applicant and will order the applicant to fully comply with the tree replacement plan within fourteen (14) days following mailing or personal delivery of the notice. The notice must be personally served or sent by certified mail, return receipt requested, to the applicant and must notify the applicant that, absent an appeal pursuant to subsection K3 of this section, unless full compliance with the tree replacement plan is achieved within fourteen (14) days from the date of mailing or personal delivery of the notice, the village may proceed to perform or cause to be performed work the village forester determines necessary to achieve full compliance with the tree replacement plan.
2.   Opportunity To Comply: Absent an appeal pursuant to subsection K3 of this section, within thirty (30) days following mailing or personal delivery of the required notice, the applicant must take action as is necessary to strictly comply with and implement the tree replacement plan.
3.   Appeal: Within fourteen (14) days following personal delivery or mailing of the required notice, the applicant may appeal the village forester's determination by filing a written notice of appeal with the village administrator. The filing of an appeal will toll the thirty (30) day period in which the applicant is required to take action pursuant to subsection K2 of this section from the date on which the village administrator receives the applicant's notice of appeal. Upon receipt of a notice of appeal, the village administrator will review all reliable and relevant documents and information pertaining to the village forester's determination.

(Ord. 2008-22, 9-9-2008; amd. 2009 Code; Ord. 2011-23, 11-28-2011; Ord. 2022-10, 3-28-2022)

10-11-8: TREE PROTECTION PLAN:

A.   Plan Required: If a regulated activity includes construction activity, the applicant must, in addition to the tree replacement plan, submit a tree protection plan with the tree permit application.
B.   Construction Activity Area: The construction activity area is the area of the subject property that is the smallest area reasonably needed to undertake the proposed construction activity as determined by the village forester. The construction activity area must include the entire area affected by the proposed construction activity and must also include any access route across the public right of way and the private tree preservation area. Construction activity must not be conducted or staged in any area of the subject property located outside the construction activity area. No excess soil, additional fill, liquids, or any construction debris may be placed or located outside the construction activity area. Any temporary buildings, structures, and driveways constructed for or associated with the construction activity must be located so as to reasonably involve the least amount of damage or removal of trees, but must nevertheless be consistent with minimum building setback requirements of this title.
C.   Contents Of Plan: A tree protection plan must consist of a site plan of the subject property upon which the information described in this subsection must be graphically and accurately marked.
1.   Location of the subject property, including street address and legal description.
2.   Existing and proposed contours of the lot on which the construction activity is to take place.
3.   Existing and proposed buildings or structures on the lot.
4.   Proposed building elevations, if applicable.
5.   Proposed work access areas and routes.
6.   The name of the general contractor or project representative, if any, responsible for the proposed construction activity.
7.   A demonstration of the ways in which the applicant will ensure that the tree protection required by this section will be achieved.
8.   A tree inventory for the subject property, consisting of a list of the following trees, identified by tag number: a) all the existing protected trees on the subject property; b) all trees on adjacent properties that are within ten feet (10') of the property line or that have a critical root zone extending into the subject property; and c) all public trees adjacent to the subject property or that may be impacted by any regulated activity. The tree inventory must list, without limitation, the following data for each tree: tag number, species, size in dbh, condition rating, form rating, and any observed problems.
9.   A tree survey for the subject property, which depicts the location and tag number of each tree described in the tree inventory. The tree survey must include, without limitation, a legend referencing the tag number, dbh, species, general condition, and proposed disposition of existing protected trees located on or near the subject property and trees other than protected trees that are reasonably likely to be damaged or removed during the construction activity. The tree survey must also depict the planned location of all proposed trees to be planted or replanted on or near the subject property pursuant to the tree replacement plan.
10.   An action plan for the subject property, consisting of a listing of the trees on the subject property, in chart form, that identifies each tree by tag number and shows, for each tree, the following information: species, size in dbh, condition, form, percent of critical root zone saved, and the anticipated damage, removal, tree protection measures, or other action to be taken regarding each tree.
11.   Detailed specifications for maintenance and protection of protected trees and for the maintenance and protection of trees other than protected trees that are reasonably likely to be damaged or removed during implementation of the proposed construction activity, including, without limitation, proposed measures such as construction pruning, root pruning, critical root zone protection, installation of a retaining wall or high visibility fencing, and auguring of utility lines when auguring is determined by the village forester to be necessary to improve the chances of tree survival.
12.   Detailed specifications for tree protection fencing on the subject property, to be placed at a minimum: a) along the property frontage from property line to property line to completely separate the construction activity area; and b) around the critical root zone of each protected tree. These specifications must also include the identification and clear delineation on the site plan of the construction activity area and the tree protection area and their respective perimeters.
D.   Protection Area: The tree protection area is the area of the subject property not included in the construction activity area. No construction activity may be conducted in the tree protection area. All reasonable measures and protective materials must be employed to preserve and safeguard trees located within the tree protection area. Protective materials must include, without limitation, the temporary installation of high visibility fencing or other similar materials in the sizes and at the locations specifically approved by the village forester. All protective measures and materials must be in place and approved by the village forester prior to the commencement of any construction activity. Protective materials may not be removed until the village forester approves the removal after the completion of all construction activity. No attachments, fences, or wires, other than those approved for bracing, guying, or wrapping, may be attached to any protected tree during the construction activity.
E.   Stop Work Order:
1.   If the protective measures and materials required by this section, or any other related measures or materials otherwise required by this chapter, are not fully implemented and completely constructed prior to commencement of construction activity, the village forester or the building commissioner may issue a stop work order until the applicant fully complies with the requirements of this chapter.
2.   If protective measures and materials constructed and employed on the subject property are not adequately maintained in a manner that protects protected trees and the tree protection area, the village forester may issue a stop work order until the measures and materials are repaired, restored, and constructed to the satisfaction of the village forester. (Ord. 2008-22, 9-9-2008)

D.   Notice Of Dangerous Or Diseased Trees: Whenever a dangerous tree or diseased tree is found to exist, the village forester will cause notice of the nuisance to be served upon the owner and the occupant of the property where the dangerous or diseased tree is found, and will order the owner and occupant to abate the nuisance within thirty (30) days following mailing or personal delivery of the notice. The notice must also: 1) notify the owner and the occupant that, unless the nuisance is abated within the thirty (30) day period, the village may proceed to abate the nuisance, assess the cost thereof against the property owner or occupant, and impose a lien for the cost on the affected property; 2) include a copy of this chapter, 65 Illinois Compiled Statutes 5/11-20-12, the identification of the property, by common description, and the subject dangerous or diseased tree or trees; and 3) be personally served or sent by registered mail to the person to whom was sent the last preceding general tax bill for the property upon which the dangerous or diseased tree is located. A copy of said notice must also be mailed to the occupant of the property if the occupant is not the same person to whom the notice is addressed.
E.   Abatement Procedures; Lien Provisions: Within thirty (30) days following delivery or mailing of the notice required by subsection D of this section, the owner or the occupant of the property must cause the nuisance to be removed or otherwise abated. If the owner or occupant neglects or refuses to abate the nuisance as required by the notice issued pursuant to subsection D of this section, the village forester will promptly cause the abatement of the nuisance by village employees or contractors. If the village forester so causes the abatement of the nuisance, all direct or indirect expenses incurred in connection therewith, including the cost of collection, will be assessed against the property owner. In the event the expenses are not paid upon billing, the village clerk, not more than sixty (60) days after performance of the work, may file a notice of lien against the property for the amount of the expenses in the manner provided by statute.
F.   Determination Of Diseased Trees: The village forester may, from time to time, conduct tests, analyses, and inspections as the village forester determines necessary to determine the existence of diseased trees throughout the village.

10-11-11: APPEALS:

A.   Overview: The appeal procedure is provided as a safeguard against arbitrary, ill considered, or erroneous administrative decisions. It is intended to avoid the need for resort to legal action by establishing local procedures to review and correct administrative errors. It is not, however, intended as means to subvert the clear purposes, meanings, or intents of this chapter or the rightful authority of the village forester to enforce the requirements of this chapter. To these ends, the reviewing body should give all proper deference to the spirit and intent embodied in the language of this chapter and to the reasonable interpretations of that language by those charged with the administration of this chapter.
B.   Appeal To Village Administrator: Appeals from any decision of the village forester may be taken by an applicant or any other person adversely affected by the decision by filing a written notice of appeal with the village administrator within five (5) days following receipt or notice of the village forester's decision. Upon receipt of the written notice of appeal, the village administrator will review the relevant evidence, documents, or information, and may receive and consider new evidence. The village administrator will render a written decision and transmit such decision to the appealing party within fourteen (14) days after receipt of the written notice of appeal. The decision of the village administrator will be final except for appeals to the board of trustees pursuant to subsection C of this section.
C.   Final Appeal To Village Board Of Trustees: In cases concerning tree replacement requiring a replacement rate pursuant to subsection 10-11-7C of this chapter of one hundred inches (100") or more, a party may appeal the village administrator's decision to the board of trustees within fourteen (14) days after its transmittal to that party by filing a written notice of final appeal with the board of trustees. Upon receipt of the written notice of final appeal, the board of trustees will review the relevant evidence, documents, or information and may receive and consider new evidence. Within thirty (30) days after receipt of the written notice of final appeal, the village board of trustees will render a written decision at a regularly scheduled meeting. Such decision may reverse, affirm, or modify, in whole or in part, the action appealed from and may include such order or determination as, in the opinion of the board of trustees, is proper to be made in the circumstances. If no regularly scheduled meeting occurs within thirty (30) days of receipt of the notice of final appeal, the board of trustees will render its written decision at the next regularly scheduled board meeting thereafter. The written decision of the village board of trustees will be final.
D.   Stay Of Regulated Activities: The filing of a written notice of appeal pursuant to this section will operate as a stay of the regulated activities related to that appeal, and no such regulated activity may proceed until a final decision is rendered on the appeal pursuant to this section. (Ord. 2008-22, 9-9-2008)

10-11-12: PENALTIES:

Any person who neglects or refuses to comply with, violates, or assists in the violation of any of the provisions of this chapter, or any order, permit, or notice issued pursuant hereto, will be subject to a fine of not less than twenty five dollars ($25.00) nor more than the maximum provided in section 1-4-1 of this code for each violation. Each tree which is removed or damaged will constitute a separate violation. Each day any violation continues will constitute a distinct and separate violation. In addition to the penalties provided in this section, any damaged or removed tree must be replaced pursuant to the tree replacement requirements of this chapter. (Ord. 2008-22, 9-9-2008; amd. 2009 Code)

10-11-13: APPENDIX A, SPECIES RATING GUIDE:

The intent of this guide is to identify tree species by genetic quality and community value and to assign them to a species group based on these two (2) criteria. The species groups are noted as A, B, C, and D. Species group A is the most highly rated group. Species group D is the lowest rated group and includes the tree species that are not protected in this chapter. The species rating guide is the basis for assessing the relative value of trees to be protected and mitigated if they are damaged or removed.
This guide represents the tree species that are considered to be the most common tree species in the community. This guide is not an attempt to list all tree species that could successfully grow in the community. In the event that the village forester encounters a tree species that is not listed in this rating guide, then it shall be the responsibility of the village forester to assign that tree species to the appropriate species group.
